We cooked the spaghetti in boiling salted water, as normal. Then Caitie combined 50g melted butter with 1 teaspoon of Marmite and a teaspoon of the pasta water.
It's a lot harder than you think to mix Marmite with melted butter!!
Then we mixed the Marmite mixture in to the pasta. It was a very subtle flavour...
We added plenty of grated parmesan cheese which helped, but frankly I didn't think it was a hit. It was vaguely Marmitey, a bit greasy (from the butter) and fairly cheesy. Caitie's dad and I decided to give it a miss, but Caitie and her brother ate it.
